The total aliphatic halide content of epoxy resins is reduced by heating a resin containing hydrolyzable halide or bound halide or both hydrolyzable and bound halide dissolved in a solvent system containing at least one polar aprotic organic solvent which is not a ketone and at least one compound containing at least one aliphatic hydroxyl group per molecule in the presence of a suitable basic-acting compound for a time sufficient to reduce the total undesirable halide content.
